Branching fractions and CP asymmetries in B0 → K +K-Ks 0 and B- → K+Ks 0Ks 0
The branching fractions for charmless decays of B mesons into the three-body final states B0→K+K-K 0 and B+K0 sK0 s was measured. It was found that the branching fractions and CP asymmetries were extracted in unbinned extended maximum likelihood fits. It was found that the K+K-K0 S final state was dominated by a CP-enev component. The contributions from the signal reconstruction efficiency and form the modeling of the efficiency variation over the space was included to measure systematic uncertainities in the branching fraction.
